I meet a CEO of a company. Having attitude like he knows everything. And give speech on any topic. But speech won't match the topic at any condition.

I meet him I asked what project do u have and all.... He showed me some website projects... With source code it was fine to me...

The thing is before showing the website project. I asked him in which backend language Website are developed...

Answer: php. I ohh php ok.
And he suddenly replied we have also used HTML & CSS.. 😵 😵 I was shocked I thought wtf?? how can a website can be developed without HTML & CSS...
